OK, I've got an older 8 ohm Eden CX1015. It originally had a coax 10, and a 15. The coax was replaced with an Eminence Beta 10. I have a spare 8 ohm Eden XLT lying around. I think that would make the impedance 5.33333 ohms. What would the advantages be of swapping it for the Eminence? Oh, I'm running a WT400 into it.
